Exosome-Mediated miRNA Delivery Service
Exosomes are nanoscale membrane-bound vesicles secreted by cells, characterized by excellent biocompatibility, low immunogenicity, and efficient transmembrane delivery capacity. They are widely involved in intercellular communication. MicroRNAs (miRNAs) are small non-coding RNAs approximately 22 nucleotides in length that regulate gene expression by targeting mRNAs. MtoZ Biolabs offers high-purity exosome isolation and purification services, along with efficient miRNA loading strategies, to support the construction of stable and reliable exosome-based miRNA delivery systems.
Exosome-mediated miRNA delivery service utilizes exosomes as natural carriers to encapsulate functional miRNAs for downstream delivery studies. This service is widely applicable to various research contexts, including miRNA functional studies, signaling pathway regulation, validation of miRNA roles in disease models, and modulation of cellular phenotypes. Exosome-mediated miRNA delivery enables targeted, low-toxicity interventions, providing a powerful tool for molecular mechanism exploration and biological function validation.

Services at MtoZ Biolabs
Based on advanced analytical platforms, MtoZ Biolabs has launched the exosome-mediated miRNA delivery service focusing on exosome-based miRNA delivery. We utilize electroporation and chemical transfection methods to load miRNAs into high-purity exosomes, and employ quantitative approaches to assess loading efficiency. This service provides high-quality carrier preparation to support subsequent cellular delivery experiments, facilitating miRNA functional research and delivery system development.
Analysis Workflow
1. Exosome Isolation and Purification
High-purity exosomes are efficiently extracted from cell culture supernatants or biofluid samples using techniques such as ultracentrifugation, size exclusion chromatography (SEC), or ultrafiltration.
2. miRNA Loading
Target miRNAs are efficiently loaded into exosomes via electroporation, electrotransfection, or chemical transfection methods. Loading efficiency is quantitatively evaluated to ensure reproducibility.
3. Quality Validation
Post-loading validation includes assessment of particle size distribution and miRNA loading levels to ensure the stability and consistency of the delivery system.
